" The abutting ends of the respective segments may be formed up tooverlap in the fashion with the rectangular contour shown in dot-ted,which the corresponding ends are spaeedly interconnected by a pair ofoppositely disposedstrut members ofangular profile such as 28. Thisframework provides for a squared fenestration 29 therethrough which isintended to register with the air-flow opening when said framework issuperimposed upon the radiator shell.

In the present instance, the profile of these respective frame segmentsis L-shaped although it might also be made to conform to Z-sh'ape orlike modifications. It is intended to form up suitable sheet-metal"strips of the desired angular shape which are then cutoff into therequired lengths.

These elements are placed end to end with one profile legof said L-shapeplaced in a common plane to constitute an'endless brim flange designated30 (see Fig.4). The respective appendant other legs of said profile areall disposed in outstanding endwise relationship to one side face of thebrim flange to provide an endless web-like flange 31.

represented in Fig. 5 and of which the seam 32 is thereupon welded orotherwise adjoined.- As originally assembled, the brim flange ispreferably extended to conform outline, and which, subsequent towelding, is trimmed'to round off thecorner regions and make the brimflange perimeter overlappingly fit the marginal shell bead '25. 'Saidbrim flange may be provided with a series of marginal apertures such'as33 serving to receive fastening bolts 34. .Each such bolt is separatelyscrewed into a tapped pronglike lug 35 that overhangs the core sheath22. The two lowermost bolts may cooperate from the support arm 20.

A trough-shaped slat rack 36 may be dc-- tachably secured'alongside eachof the outstanding legs of the top and bottom frame 7 like transverseprofile having end trunnions "to open inwardly 7 toward the core.

segments 26 and 27 in the aligned fashion ind cated in Fig. 2.Aplurality of vertical shutter slats such as 37 are mounted between saidcomplementary racks and given a' bowthat align withone slat edge. Saidslats may be actuated in unison by any suitablemeans A shroud-like plate38 may be fixed exteriorly to cover each of the respective framesegments and mask therebehind both the racks and the Welded seams 32.Thisplat'e is preferably fluted vertically in bow-like profile tocorrespond with the slat configuration.

As is apparent from Fig. 2, the bottom-' mostcontour of the housing wall14A is cut I that the shutter frame should be removed, 1 such platesbeing suitably apertured to permit of freely entering the fasteningbolts. It will be observed that my present framework is arranged towholly confine-the shutter installation within the housing extension Eandthat said'shutter assembly may be bodily detached without removingthe radiator shell, thus providing an advantage over the conventionalinbuilt shutters housed within and secured internally of the shell.

Referring now to Figs. 6 and .7, this modified shutter design is moreparticularly suited toheavy-duty bus and truck purposes. Here theradiator shell lOis preferably made up as a casting having an inturnedflange 41 of which the marginal edge is faced rearwardly toward the coreand again provides for a substantially rectangular opening therethrough.This framework is likewise builtup out of relatively heavy sheet-metalor cast strips having an L or Z shaped profile. the strip ends beingmitered as at 42 and welded together to constitute an endless brim flan43 and a rectangularly disposed web-like gions is initially kept squareas'shown in dotted outline at 45 and which corners are preferablyrounded off after welding together the frame segments. The'perimeter ofthe trimmed flange 4:3 is made to telescopically fit into the shellopening in such fashion that said flange stands inwardly somewhat fromthe plane of the inturned shell flange 4-71.

It is preferred to correspondingly modify the method of framesecurementand to this ,end, the perimeter ofthe brim. flange 43 is oppositelynotched out at as 46 to cooperate with'the radially disposed S shapedretaining clip 47. Oneterminal thereof is shown fixedly secured to theflange, while the-outeu' most end thereof is apertured to receive thescrew fastening 48 which in turn is entered into'the inturned flange 41.This modified disclosure otherwise conforms to the previously described.shutter arrangement and again allows of effecting production econo'miesin building up a framework,in'relatively small quantities to meetvarying requirements in shutter sizes and the like.

7 Thejdescribed angular disposition of my only serves to impartaugmented lateral rigidity to said flange, but also affords con-.7
